I have this nylabone and about 15 others, all different kinds. All of my dogs love them. Once the ends start getting worn I replace them, but that usually takes a couple months. Mine also get antlers, kongs, rope toys and stuffed toys. I watch the rope toys and stuffed toys and they only have those when I'm home.
